Description of the invention (I) Detailed description The present invention is based on a surface treatment method of a treatment object (especially a ribbon) made of special steel, wherein the treatment object is used in at least one container-an erosion solution Process and rinse. Special steels (they are stainless or rust-proof alloy steels) must have a metallic clean surface with a small depth of roughness and K to achieve the best chemical resistance. In order to achieve this, the rust layer M and the tempering color (Anlauffarbe) generated during hot forming or heat treatment must be removed by an erosion process, because these have a negative effect on the formation of a passivation layer that prevents corrosion. And in the special bracelet, this rust layer and tempering color are also removed by the erosion process. However, in this erosion process, it is necessary to consider that the substrate metal is strongly resistant to acid attack, and where the acid is highly corrosive, the surface will not dissolve uniformly, but will dissolve strongly locally. Therefore, the existing mirror layer will adhere more firmly to the base metal, so it is much more difficult to remove and can only be done at a higher cost. In addition, in the case of special gongs, it should be considered that the lure contains, in addition to iron oxide, oxides of alloyed metals and mixed oxides. In addition, it is necessary to consider, for the erodibility of special steels, its state of organization (it can be Vostian type, fertilized iron type, Asada loose iron type * Vostian one ferrous iron type, and one fertilized one Asada loose iron type) is also important. Taking these conditions into consideration, steel strips made of special steel were first mechanically derusted by spraying and brushing. Then the steel strip (depending on the state of the organization) is used in several containers with different erosion solutions, such as sparse acid, hydrofluoric acid, M and no nitric acid additives, mixed acid (hydrofluoric acid-nitric acid mixture) or sulfuric acid Or Neutral Plutonium Electrolyte Tank-3- This paper size applies to Chinese National Standard (CNS) A4 (210 X 297 mm) (Please read the precautions on the back before writing this page).

The preparation of the method is not a reasonable way to pre-treat the cheap acid program. It is the least reasonable. The use of special steel will have the so-called chloride but may not exist. Ejection process. Full It is relatively easy to use this, and it is also not the invention when it is processed (especially it can be omitted, and it will produce this purpose. With at least some erosion after washing, it is troublesome to compare or regenerate this.) The purpose of water is the belt type, which can make the operator more than 3, in the past, this special solution is expensive. For the troublesome time, there will be people who use it today. It is the mention. A kind of acid is treated as a single acid in a container with a special steel belt to passivate it. Therefore, it is expensive to treat the special steel composition in the used erosion solution. In addition, it must be Kalu, where the sludge sedimentation, it needs to be done. Erosion of expensive waste to special steel for erosion treatment provides a method for surface treatment of special steel, in which machinery has a particularly good reproducibility of relatively waste water. But it is also necessary to ensure the roughness value on erosion In the method, the dissolution obtained according to the present invention is used as an erosion solution, and it is generally known to use the erosion solution of the acetic acid to spray the acetic acid as the erosion solution, but it has not been used for the erosion treatment so far. This is due to the risk of interstitial corrosion and / or intergranular corrosion in the treatment of special rhenium with osmic acid, as the resulting steel generally erode special steels. Studies have shown that in this method of the present invention, this danger and A solution containing only osmic acid as the acid has a higher efficiency. The use of the solution can make the treated object have a particularly smooth surface, and its roughness does not exceed -4-. %)

Description of the invention (γ) The enlarged schematic diagram of the processing container is shown in the second and third figures. According to the second figure, the processing vessel ⑵ is composed of a plurality of parts or electrolytic tanks [which have individual electrodes 设置] arranged in front and back. Here, the individual electrodes ⑷ in the successive electrolytic cells ⑶ alternately constitute the anode and the cathode, while the steel strip ⑴ also alternately constitutes the cathode, the anode, and the cathode in the relevant electrolytic cell ⑶, and the steel strip ⑴ is A cathode and an anode are formed in the relevant electrolytic cell ⑶, in other words, alternating cathode and anode erosion is caused here. If necessary, the polarity of the electrode ⑷ in the following part or the electrolytic cell ⑶ can be changed in a short period of time (for example, within 1 to 2 seconds) through a polarity switch or a polarity changeover switch. The third figure shows the processing vessel ⑵, in which the erosion effect is achieved by the so-called "medium conductor method J. Here, the processing vessel ⑵ is likewise divided into individual electrolytic cells ⑶ or portions having cathodes and anodes arranged on alternate sides. This The point also makes the polarity of the steel strip ⑴ change repeatedly when it is pulled through the electrolytic cell, which can prevent the hydrogen from being electrolyzed and the brittleness caused by the erosion. It will not be released because the polarity of the electrode changes alternately * In the design of the second figure and the third figure, the treatment container 充 is filled with an erosion solution, which contains only osmic acid as the acid, wherein the erosion solution contains about 70 ~ 140 grams, and preferably about 90 ~ 1 20 grams of free acetic acid per liter of contact dissolution. The temperature of the erosion solution is about 50 ~ 95 ° C, and preferably about 70 ~ 8 5 ^ 0. During the electrolytic treatment, the current density is about 3 ~ 40 amps / cm2. Inch, and preferably about 20 amps / square inch. As an electrolyte, the erosion solution should contain about 30 ~ 200 g / l of iron oxide content. -6-This paper size applies the Chinese National Standard (CNS) A4 size (210 X 297 mm) (Please read first Please fill in this page before filling out this page) Pack----- III Order 1!

Here, if the erosion solution flows to the steel belt ⑴ In the opposite direction, it is very suitable. In this processing container ⑸, the concentration and temperature of the erosion and dissolution are approximately equal to those in the processing container 。. If necessary, a treatment can be set between the processing container ⑵ and the processing container ⑸ Container (not shown), which is designed in the form of a so-called spray processing container ⑹, just as it is in this case * after the processing container ⑸. In the processing container 设 located behind the processing container ,, the steel strip Pressurized spray with an erosive solution containing osmium acid. The erosive solution sprayed here and the treatment solution of ⑵ and ⑸ are the same. After processing the container ⑹, the steel strip Go to Yishen Washing Container ⑺, in which all remaining chlorides still on the steel strip ⑴ are removed. In this flushing container κ, it is advantageous to use completely dehydrated water. The flushing container can be designed to be invasive and / or After spraying the container 式, the steel belt ⑴ is also guided through a passivation device 宜, which should have argon peroxide. Then the belt ⑴ only needs to be dried. The above embodiments can be changed. Only the spray treatment of the steel strip ⑴ is performed in at least one container 如此. In this way, the spray treatment can be combined with only one immersion treatment or one electrolytic treatment. If necessary, it can be performed after the spray treatment of the above embodiment. One immersion treatment, which can be followed by another spray treatment. -7- This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) ----------- -Installation 丨 丨 ---- Order —.------ Line_ (Please read the precautions on the back before filling this page)
